you can also just use bookmarklet (or multiple defining different prompts):

    function __summarize(api_key) {
        var selection = window.getSelection().toString();
        if (selection.length == 0) return;
    
        var xhr = new XMLHttpRequest();
        xhr.open("POST", "https://api.openai.com/v1/chat/completions");
        xhr.setRequestHeader('Content-Type', 'application/json');
        xhr.setRequestHeader('Authorization', 'Bearer ' + api_key);
        window.scrollTo({top: 0})
        document.body.innerHTML = 'asking...'
        document.body.style.backgroundColor = "white";
        document.body.style.color = "black";
        document.body.style.fontFamily = 'monospace'
        document.body.style.fontSize = "16px"
        document.body.style.margin = "auto"
        document.body.style.padding = "1rem"
        document.body.style.maxWidth = "60rem"
        xhr.onreadystatechange = function() {
            if (xhr.readyState == 4) {
                if (xhr.status == 200) {
                    var response = JSON.parse(xhr.responseText);
                    var summary = response.choices[0].message.content;
                    document.body.innerHTML = summary
                } else {
                    try {
                        var e = JSON.parse(xhr.responseText);
                        document.body.innerHTML = e.error.message
                    } catch(e) {
                        document.body.innerHTML = 'error asking.. check the console'
                        console.log(xhr)
                    }
                }
            }
        }
    
        var data = JSON.stringify({
            "model": "gpt-3.5-turbo",
            "messages": [
                {"role": "system", "content": "Summarize the following text as if you are Richard Feynman"},
                {"role": "user", "content": selection}
            ]
        });
        xhr.send(data);
    }
